LAUNDRY TRAY 'Appncationried aprii 25,

rlhis invention relates to improvements in laundry trays and moreparticularly to a combined drainage and trap fittingv for such trayswhich is designed with particular ref- 5 erence to the requirements oftrays formed with a plurality of compartments.

@ne object of the invention is a fitting of the kind generally describedwhich is compact in construction and which as a'result 1o thereofpermits of ready access for purposes of installation and cleaning. Aturtherobject is a fitting which is partially embedded in thebottoin ofthe tray when `it is cast, such a construction elimii5 natingpossibility of mistake 'in thesize of trap selected at the point'ofinstallation and also enabling a saving in labor costs.

A stillrrfurther object is a fittingwhi'ch is self-cleaning. 2o The`invention is illustrated in the accompanying drawings, .inA which Figure1 is a sectional view of a fitting coni structed in accordance with theinvention,

as applied to a two-tray laundry unit,

irr- FcE fitting is partially embedded in the tray when cast. In Figure1 a tray having two com partments A. and B is cast as a unit, thecom Vpartments being separated bythe partition @,while in Figure 2 the traycomprises three compartments D, E and F cast as a unit, the intermediatecompartment E being separated from the compartment D by a partition AGand from the compartment F by "a parti` .tion H f' The fitting,asillustrated, in Figure 1 is partially embedded in the tray beneath thepartition C. It includes la hollow body 11 (Fig. 4) which extendslengthwise of' the said partition and is provided with transverselyextending drainage arms 12 and 13 which are formed on'a common curve.The said'arms extend to either side of the partition C, the arm 12beingin communication through its mouth 14 with the compartment A and the Iarm 13 being in communication through its mouth 15 'with the oppositecompartment B. The partition C is provided with overflow openings J nearits top which communicate with a downwardly extending overow passage Kwhich is formed in the partition. The i Apassage K is in communicationwith bothof the drainage arms-12 and 13 by virtuel of a duct 16 providedby a hollow rib 17 formed upon and straddling the body 11 of thefitting,

the said duct opening into the arm 12 as at 17a, into the arm 13 as at18 and being inconi" i munication with the overflow passage K throughVan opening 19 formed between the ends of the rib 17. l 4

When the fitting is appliedfto a three comT partment tray as illustratedinxFigure2, it

includes an elongated tubular branch or extension 20 "which" may4communicate with either of the drainage armsfofthefitting.` In theillustrated embodiment, the drainage branch is connected at its innerVend to the arm 12 and is provided at its opposite end with a dischargemouth 21 which is Vin com-1 munication with the compartment D. Thebranch 20`is provided with a second discharge opening '22 whichcommunicates with the overflow passage inthe partition G. The extension20 is preferably tapered toward its innerend and is inclined downwardlyfrom v themouth 21 to the point at which it is connected to the arm 12thereby to facilitate the drainage iow of the water in the compartment Dand to deliver such water to the arm 12 at a point and in a directionwhich will prevent backing` up in either of the other two compartments.The tapering of the eXtension accelerates the How of water through itand facilitatesthe continuous removal of the solid materials. 1 y

a In accordance with the invention, the body 11 is formed with adownwardly extending. portion 23 (Figs. 5, 7 and 9) which provides achamber 23a common to both ydrainage arms and through which all of thelwater from the various compartments of the tray must pass on its way tothe discharge nipple 24. the latterbeing an extension of the body of thefit ting.. The chamber 23a is divi dedby a wall 25 into inlet andoutletparts 26 and 27 respectively. Communication between the two saidparts is afforded bv an'opening 28 in the wall 25 at the bottom of thechamber. Thus, using either Figures) or 10 for illustration, water fromthe tray entering the arm 12 either through its mouth 14 or theoverflow/mouth 17 passes from the inlet part 26'V of the chamber throughthe opening 28 into the outlet part 27 of theV chamber and out throughther nipple 24. I i

From the foregoingit will be apparent that as the water fromeither ofthe drainage arms must enter the inlet side 26, pass through the opening28 and up overthe dam .providedby the wall 25 before it' can dischargethrough the nipple 24, a trap is provided in which water is maintainedsubstantially at the level indicatedin Figures 8 and 9, this 'body ofwater sealing the passages between thewaste pipe line andthe tray. Anopening may 'be found in the bottom of the'body portion 26 of thefitting for cleaning purposes, which Y opening be suitably closed as bya threaded plug 22a. Y

One method by which the fitting may be connected to the waste pipe isshown-in Figure Bin which ears 29 are formed on theV nipple 24, theconnection between the waste .pipe 30 and the fitting 'being effected bya clamping ring l31 and suit-able nut and bolt fastenings.

It is to be noted that the passage whichthe waste watertarhes throughthe trap'is such as to facilitate its rapid flow and hence preventsettling of solid materialsinthe bottom: of the fitting. Further, theduct 16, when not availed of in 'its overflow capacity permits miXingofair'with the water before it enters the chamber 23a and hence preventsthe water The combined'trap and Vfitting is compact `in construction andthis Ytogether with the fact that it is partially embedded in theV traywith which it is associatedfresults in' additional Vspace beneaththetray and thereby enables ready access for purposes of installationand cleaning. The combination of a trap and drainage fitting asa part ofthe tray has the further advantage that time and labor is saved inVinstallation and possibilty of the wrong size trap being selected forany particular tray is eliminated. Y

In combination, a laundry trayunit and Y a combined drainagel and trap fitting cast in the bottom ofsaid unit, said fitting having a' hollow body which provides a chamber,a drainage arm in communication with a compartment of said tray and withsaid chamber and a second drainage arm in communication with anothercompartmentof said tray and with said chamber, said body being formedwith an outlet passage'which extends from said chamber from a; pointabove the openings of communication between it and said drainage armsthereby to enable sealing of said openings. f
